'Pegaso3 Marving Pipes' - NOT !!!!
Daves Aprilia Pegaso Webpage

We were sold these by an Italian guy (in Italy) who said they were Pagaso3 Pipes, straight replacement, loud.... He couldn't have got it more wrong if he'd tried....
They wouldn't fit in anyway, the pipes were too long, or too short, wrong bends, wrong mounts..everything.

In the end I got hold of some Flexible Stainless Exhaust pipe (32mm inside dia.) from a manufacturer in the UK, and made my own pipes...
See Below for pics...

NIGHTMARE !!!!! and still they are not loud enough.. Look good though !!
